Low avalanche danger exists for all aspects and elevations as we begin to build our snowpack. Shallow buried objects such as rocks, stumps, brush and sticks will be the most notable hazards today. Thick, wet and variable snow will also make skiing challenging. Take it easy and don't let early season excitement cause injury!

It's snowing on Mt Shasta! We are looking forward to the season and hope you are too. Avalanche advisories will begin Friday.

GET EDUCATED! The MSAC's FREE Avalanche Awareness and Companion Rescue Clinics will continue this season as well as our Snowmobile Avalanche Awareness / Companion Rescue Workshops! Our first set of presentations and clinics will begin this Friday/Saturday. See our "Events" link for details. See you all soon & wax'em up!

Overall, LOW avalanche danger exists for all aspects and elevations on Mt Shasta. The avalanche danger will rise to MODERATE for all elevations on E - SE - S - SW aspects in response to above freezing overnight temperatures and warm daytime highs. Small to medium size human triggered loose wet avalanches are possible during the warmest portions of the day. Natural avalanche activity is unlikely but not impossible.

Small to medium size human triggered loose wet avalanches are possible during the warmest portions of the day. Natural avalanche activity is unlikely but not impossible.

MODERATE avalanche danger may form on sun exposed E-SE-S-SW-W aspects during the warmest portions of the day, especially above treeline. Loose wet snow avalanches will be possible on slopes steeper than 35 degrees. Larger slab avalanches remain unlikely, however small to medium wind slab avalanches triggered by a skier/climber will be possible today.Overall, LOW avalanche danger exists for all other areas.

Use caution on mid to upper elevation NE-E-SE, wind loaded slopes, steeper than 35 degrees. The avalanche danger will increase as more snow is added to the snowpack from the current storm and wind loading.

The avalanche danger is LOW for all elevations and aspects. Normal caution is advised.

Carry an avalanche beacon, shovel, and probe and know how to use them when traveling in the winter backcountry.

Snow conditions on Mt Shasta are smooth and firm in the AM hours. This poses risk for a long slide for life should one slip and fall. Ice axe, crampons and self-arrest skills are required for a safe climb...and ALWAYS wear a helmet!
